Scanxiety.

Scanxiety. noun, feeling ; the immense horror and panic after a check-up MRI scan to see if one's organs, limbs (Grace specific: BRAIN) are working correctly and not subject to further treatment and thus more upending of patient's life.

The worry that the scan results, always announced a long time (1 week – 10 days) after, will yield disappointing(/hideously overwhelmingly evil) news. 

Grace's experiences with Scanxiety:

2014, bad. Life-altering. 

2015, bad. Anger-inducing.

2016.............. 'Stable', a.k.a. satisfactory, if vague.

(The term Scanxiety first coined by Grace's hospital bestie G.Wood)
